Hesus cordatus ( FABRICIUS 1803) ( Fig. 3 , 9, 10 , 22 ; photo 3, 4)

Described as Aradus cordatus from «America meridionali«, later assigned tu Hesus by STÅL 1862. CHAMPION 1898 synonymized in his great comprehensive work «Biologia Centrali-Americana» Hesus annuliger STÅL 1862 from Mexico, Crimia cincticornis WALKER 1873 from Brazil and Hesus semiolus BERGROTH 1894 from Brazil with cordatus. Lectotype 3, designation by HEISS 1997: 45.

This species is distinguished by a combination of characters given in the key. Its colouration is variable, generally brownish with lighter parts: antennae brown, basal half of segment III ochraceous (sometimes fading), legs with two pale rings on tibiae, of which the apical one on fore tibia is partly fading or missing. Pronotum with evenly rounded lateral margins of anterior lobe, the oblique median elevations are delimited anteriorly by round tubercles, the gap in between is depressed with only few smaller granules (fig. 3).Abdomen: anterolateral angles usually brownish, sometimes extended to basal 1/3 of deltg II-VI, their remaining parts including apodemal impressions ochraceous, posterior half of tergite VII brown. Hemelytra with a longitudinal ochraceous spot on membrane posteriorly to apex of corium (photo 3, 4). Venter ochraceous at middle, brownish elsewhere. Spiracles II-V ventral, VI lateral and visible from above, VII dorsolateral, VIII terminal. Terminal segments as fig. 9, 10. Parameres as fig. 22.

Hesus cordatus resembles strongly H. humeralis nov.sp., and was therefore confused with the latter; and therefore it is necessary to reexamine this taxon in collections.

M e a s u r e m e n t s Length 33 9.3-9.8mm, ♀♀ 9.7-10.6mm; ratio length of an-

tennae / width of head 2.6-2.7; ratio antennal segment I / segment II 1.75-1.90.
